1. Cars

If the weight of all those 10-pound ketchup bottles you buy at Costco messes up your car's transmission, rest assured that you can buy a new one and be home in time for dinner. Costco offers discounts to members through local car dealerships. It won't fit in your cart, but a bargain's a bargain.

2. Johnnie Walker 1805 Blue Label

Don't put this on your shopping list, because you've already missed your once-in-a-lifetime chance. Only 200 bottles of this special reserve were ever made, and while most were distributed by Johnnie Walker, one found its way into a Costco with a shocking $20,000 price tag. If I saw that price, I would just keep on walking.

3. A wedding dress

You can find everything you need for a lavish wedding inside the bargain store, and if you're not picky you can get married there too. That's what a pair of Costco fanatics from Australia did, saying "I do" in front of 90 guests inside a Costco warehouse.

4. Four liters of hot sauce

We all know someone who pours on a little too much of the spicy stuff, but this is ridiculous. Right now it's only available through Coscto's Business Centre branches, but customers say they've spotted these huge containers in the regular stores.

5. A $900 cheese wheel

6. A chicken coop

Costco is actually eating into their own business with this one: once customers realize they can get their eggs at home, nobody will be buying them at the store. These coops come in a range of colors and styles to suit your tastes (or your chicken's, if they're demanding).

7. Coffins

A Saturday afternoon spent enjoying free samples with your family isn't the best time to contemplate your own mortality, but you never know what's around the next aisle. If you insist on picking out your own coffin, you might as well enjoy a hot dog (or two) at the same time.
